refactor: strip no_std from kiln-runtime (phase 1: prelude + lib.rs)#168
Conversation
Remove 414 lines of cfg-gated no_std code from prelude.rs and lib.rs. The interpreter is std-only per RFC #46 architecture. Removed: - All #[cfg(not(feature = "std"))] blocks and no_std alternatives - BoundedHashMap/BoundedHashSet/BoundedString type aliases - Custom vec!/format! macros for no_std - Arc/Mutex/RwLock polyfills for no_std - option_value_as_* helper functions - All cfg gates on module declarations in lib.rs Trace: skip Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
First phase of stripping no_std conditional compilation from the interpreter per RFC #46 architecture decision.
This is phase 1 — 369 cfg blocks remain across 15 files (module.rs, memory.rs, module_instance.rs, etc.)
